Ok, I’ve tried flashing it with retsifp’s instructions, but something isn’t working.
I tried to fit all the relevant information into this screenshot:
I downloaded the .zip, opened flash.sh with Editor and deleted the last two words in there. Now the “a” is the last letter.
As you can see I’ve managed to connect my device via fastboot but like others here I wasn’t quite sure what this step means:
I assume that I’m just supposed to connect my device via fastboot and then run the “flash.bat” and it will automatically detect my fastbooted device and start flashing?
Anyways as you can see in the bottom left of the screenshot I got some kind of error message when running flash.bat. (Hope the german isn’t too confusing, it says: "The command “fastboot” is either not written correctly or couldn’t be found.) It looks like it had problems with connecting to the fastbooted device, still I was able to reboot my device by typen “fastboot reboot”, so I would assume that it was connected corretly!
It’s because ADB is not fully installed/configured on your computer.
You have to look there for example: https://forum.xda-developers.com/showthread.php?t=11617767
I followed these instructions (as you can see in the top right corner of the screenshot) and added the user variable for Minimal ADB in my advanced system settings. Do I need to edit the path to direct to the “adb.exe” or is it supposed to be the path to the whole programm directory?
Hope you guys can make somthing out of this? I’m not sure what went wrong
